my home local channels at vacation home

I  am interested in switching to DirecTV stream but have a question regarding local channels .  I have been trying DirecTV stream for a few weeks at my primary residence and am really enjoying it. The primary residence address and zip code were used to set up my account. I own a 2nd "vacation home" on a lake about 90 miles from my primary home that I use mainly on weekends. That home has two TVs that I would like to be able to use my DirecTV stream account on. The zip code that my vacation home is in does not offer the "local channels" from my primary address/zip code( in fact, it appears that there are NO LOCAL CHANNELS offered at the zip code of my vacation home????).   I want to use my DirecTV stream service  when at my vacation home and be able to watch the same local channels just like when I'm at my primary(billing) address.

I am interested in using Gemini air devices. I understand that the gemini air has location services built into it. Will it prevent me from getting any local channels or can I change the settings in the gemini air to use my "billing zip code" (primary residence) to determine my local channels when I am there??  I understand that DirecTV stream does allow up to two streaming devices connected to a TV to be accessed out of the primary home network??
